Summary:                    crash when calling ao2_unlock inside
pthread_timer_disable_continuous
Description: 
When under heavy load we have experienced random crashes (6 times in a day)
at the same point in the code. The load is with about 200 channels, 70
users and making a lot of calls. It was very stable until we started
reaching a certain level of usage.

Oh, if you're wondering what the error means, it's that the dynamic linker
failed to find the symbol called "ao2_unlock" in the PLT (procedure lookup
table).  Given that the symbol is clearly there, there is a problem in the
dynamic linker.  We cannot solve this problem within Asterisk, as the
problem is within the dynamic linking tools.

You might try statically linking Asterisk (see Compiler Flags / Static
Build) as a temporary workaround, though since it uses some of the same
tools, that isn't guaranteed to work.
